Get Driver assist systems -> Adaptive Cruise Control (ACC) Guide for Volkswagen Touran 4 Door Third Generation (2022-2025)

Introduction

Adaptive Cruise Control(ACC) maintains your selected speed. When the vehicle approaches a vehicle driving ahead,

the ACC adjusts the speed automatically and maintains your set distance to the vehicle driving ahead.

Does this vehicle have ACC?

If there is a button on the left-hand side of the multi-function steering wheel, the vehicle hasACC

.

Speed range

You can set a speed of between 20 km/h(15 mph) and 210 km/h (130 mph). The maximum speed that you can set

may be lower, depending on the vehicle equipment and country.

Driving with ACC

You can override theACC

system at any time. The regulation function is canceled when you apply the brakes. When you accelerate, the

regulation function is paused while accelerating and then resumed with the speed set.

If a trailer is hitched,ACC

is less dynamic.

Driver intervention request

If automatic deceleration by theACC

is not sufficient or the system limits are reached, the ACC will prompt you – with a message in the instrument

cluster – to also apply the brakes. The red warning light will also turn on and a warning tone will sound. Take

over steering and be ready to brake.

WARNING

ACC

is not a replacement for the driver's attention and works only within the system limitations. ACC cannot detect all

driving situations and may not react, or may react with a delay, or may react in a way that is not desired. If you are

careless, there is a risk of accidents, serious injuries and death.

● Always stay attentive and do not rely solely on the system. The driver is always responsible for control of the

vehicle.

● Observe the system limitations (→ Adaptive Cruise Control (ACC)).

● Always adapt your speed and distance to vehicles driving ahead based on the visual, weather, road, and traffic

conditions.

● Take over steering immediately if a driver intervention prompt appears in the instrument cluster display or the

deceleration by ACC

is not sufficient.

●

● Apply the brakes if the vehicle continues to roll unintentionally, e.g. after a driver intervention prompt.

Special driving situations

The functions described below depend on the vehicle equipment and are not available in all countries.

Predictive ACC

If the vehicle has a Dynamic Road Sign Display,ACC

can adjust the speed to recognized speed limits and adjust the route history .

Passing

If you activate the left turn signal(for left-hand drive vehicles, the right turn signal)to overtake, the ACC

will accelerate the vehicle and reduce the distance from the vehicle ahead. Your selected speed will not be exceeded

during this.

If the ACC

does not detect a vehicle ahead after changing lanes, then the ACC will accelerate the vehicle up to the selected

speed.

Stop-and-go traffic

ACC

can brake vehicles with automatic transmissions to a stop and hold them stationary. ACC remains active, and the

instrument cluster display shows ACC is readyfor a few seconds.

Vehicles with comfort drive Travel Assist:You can extend this time by continuing to hold the steering wheel.

As long asACC

remains active, the vehicle will automatically move again once the vehicle driving ahead starts and if no obstacle has

been detected.

Extend drive-readiness or reactivate:

1. Press the

button.

Or: Vehicles with comfort drive Travel Assist:Take hold of the steering wheel again.

Driving off when drive-readiness has ended and the vehicle driving ahead has already started moving:

1. Press the

Or: briefly press the accelerator pedal.

The ACC

button.

does not stay active in the following scenarios:

—The stationary phase lasts several minutes.

—The driver door is opened.

—The ignition is switched off.

WARNING

If ACC is readyappears in the instrument cluster display and the vehicle driving ahead starts to move, your vehicle

will start driving automatically. The vehicle may not be able to detect obstacles in the vehicle's path when this

happens. This may cause accidents and serious injuries.

● Check the vehicle's path every time before you start driving and brake the vehicle if necessary.

Right-side passing restriction (left-hand drive vehicles: left-side passing restriction)

270

Fig. 1 In the instrument cluster display: slower vehicle

detected in the left lane (general example).

Vehicles with right lane passing prevention:If the ACC

detects a slower vehicle in the left lane (for left-hand drive vehicles, in the right lane), the ACC will brake gently within

the limits of the system and prevent you from overtaking illegally. The function is available from approx. 80 km/h

(approx. 50 mph).

Vehicles without right-side passing restriction:Stop the regulation function when driving on roads with multiple

lanes if vehicles are driving slowly in the passing lane.

ACC system limitations

Limits of the sensor system

ACC

detects driving situations using the radar and ultrasonic sensors in the front of the vehicle and the camera behind the

windshield. The radar sensor has a range of up to approx. 120 m (approx. 400 ft).

WARNING

If you use the ACC

in situations outside system limitations, accidents and serious injuries may result and legal regulations may be

violated.

● Be aware of the limits of the sensor system (→ Sensor system) and stop the regulation function in the specified

situations.

Unrecognizable objects

ACC

only detects vehicles that are moving in the same direction or are stationary. The following will not be detected:

—Pedestrians

—Animals

—Vehicles crossing the street or oncoming vehicles

—Other stationary obstacles

Stationary vehicles

271

Fig. 1 Stationary vehicle.

Up to a speed of approx. 60 km/h(approx. 37 mph), ACC

only responds to stationary vehicles to a limited extent if a stationary vehicle is detected as such and there is enough

space to brake the vehicle you are driving behind the stationary vehicle within the system limitations of the ACC. ACC

does not perform emergency braking → fig. 1.

The reaction to stationary vehicles depends on the vehicle equipment and is not available in all countries.
